使用optaplanner构建quarkus本机映像时出现随机/可拆分随机错误

我搜索，有这篇文章与randoms原生图像，但我仍然不知道我需要做什么来解决这个问题。

似乎quarkus试图为drools类创建Random或SplittableRandom的实例，我使用optaplanner quarkus，我不使用drools规则引擎，我使用约束流。

在为optaplanner quarkus应用程序构建本机映像时，是否有人遇到同样的问题？我该怎么克服这个问题？我试过graalvm 22.0和21.3，它们都有相同的问题。

提前谢谢你的帮助。

Answer 1

下面这行代码告诉我你的类路径有问题：

Call path from entry point to org.drools.wiring.dynamic.PackageClassLoader.writeClass(String, byte[]): 

drools wiring dynamic模块不是为在本机模式下工作而设计的，需要用drools wiring static替换。实际上，optaplanner quarkus模块为您完成所有这些工作。

您是否使用optaplanner-qukus而不是optaplanner-core？堆栈跟踪告诉我您可能不是。如果您是，我建议您找出drools-布线-动态依赖关系的来源，并将其删除。

问题的另一个来源可能是您试图在本机模式下使用constraint DRL。这是不受支持的，并且会因一个或另一个异常而失败。在本机模式下，您有三种约束选择——约束流、Java增量或Java Easy。
